I’m Wayne. I design and build AI applications, integrations, and full-stack tools that turn complex workflows into useful software.
My projects span research automation, evaluation dashboards, browser tools, and full-stack applications, connecting messy inputs, AI models, and useful workflows.
I care about the parts that make these systems dependable: validated outputs, reviewable context, explicit state, and recovery when a step fails.
Docling · 70k+ stars
Contributed to a document-processing toolkit for generative AI, with integrations across LangChain, LlamaIndex, and the broader AI ecosystem.
Merged PR #5228 — Prevent silent content loss in HTML email ingestion
Fixed silent loss of HTML email footers by preserving content-layer semantics end to end, from the HTML backend through the email document model and JSON export. Footer content is also available through opt-in Markdown export, while default body-only output and plain-text precedence remain unchanged.
Added end-to-end regression coverage for HTML-only and multipart messages, blank plain-text alternatives, footer-only content, escaping, and consistency across the document model and export formats.
Karakeep · 30k+ stars
Contributed to an open-source bookmarking app with AI-powered tagging and full-text search.
Merged PR #3053 — Search by notes and highlights
Implemented has:notes and has:highlights filters across database queries, smart lists, and search autocomplete, with documentation and regression tests.
Merged PR #3299 — Consistent manual summary status
Updated successful manual summaries and their status in the same database write, with regression tests for recovery, inference errors, empty responses, and cross-user access.
SayAll · 2.6k+ stars
Contributed to a native macOS app that turns Bluetooth voice remotes into wireless microphones and customizable controls.
Merged PRs: #829 · #844 · #888 · #913
Fixed left/right modifier-key handling, unified native menu-bar interactions, added per-device remote battery status, and made focus-option cards fully clickable. Included regression tests and manual macOS validation.
| Project | What to look for | Stack |
|---|---|---|
| Agent Lens | Compare report quality across prompt versions. Inspect human review, judge calibration, and cost/latency tradeoffs. | Python · FastAPI · React |
| Signal Workbench | Run an offline research pipeline with synthetic crypto evidence, proposal validation, budget fallback, and resumable local delivery. | Python · SQLite |
| Reply Copilot | AI writing assistance inside the browser, with reviewable context, explicit site access, and protection against overwriting newer drafts. | JavaScript · Chrome MV3 |
| CloseLoop | A decision-management PWA with explicit state transitions, preserved reasoning, and separate data/asset caching. | TypeScript · React · D1 |
Also building Agent Title Renamer: a portable skill for keeping AI conversation titles useful and consistent.
Away from the keyboard, I share my home with four cats. They also supervise the keyboard. (´•༝•)`
- Make behavior inspectable. Small modules, documented decisions, and examples you can run locally.
- Test the failure paths. Invalid model output, stale editor state, interrupted delivery, and data boundaries deserve explicit handling.
- Connect architecture to delivery. System boundaries, integration choices, APIs, and data pipelines through to the interface people use.
Tools I reach for: Python, FastAPI, SQLAlchemy, SQLite, TypeScript, React, Chrome extensions, Cloudflare Workers, D1, and GitHub Actions.
Open to remote opportunities in solutions architecture, AI applications, research tooling, data automation, and full-stack development. Comfortable with asynchronous collaboration in English and Mandarin.
